And who causes this? Israel – when they receive one from the other, whether in Torah, whether in money, they cause one to receive from the other ‘above’, and for one to bestow to the other. And all by means of ‘channels’. It is this that is written: (Ps. 42:8) Deep calls to deep, to the sound of your channels... etc.
And what do they say, one to the other? ‘Express your waters! I hear the sound of two friends.’clx
And they correspond to the two lips, which are called: (Ps. 42:2) the streams of water. And what are they? Netzaḥ and Hod, which are called: (Gen. 30:38) the irrigation-troughs of water, and both-of-them are irrigated, by means of that channel which is the Middle Pillar, which includes all, and it is the covenant (Yesod) – which incorporates all the limbs of the body.
